   A network architect is designing a highly available L3 gateway for a pair of servers using a Dell SONiC switch. The servers are in two different subnets (10.0.1.0/24 and 10.0.2.0/24) and must use the same physical interface on the switch as their gateway. The architect wants to minimize the number of IP addresses used and avoid any dependency on external protocols. What is the MOST efficient configuration?

   • AAssign a /23 address to the interface to cover both subnets
   • BAssign a primary IP address for one subnet and a secondary IP address for the other subnet on the same interface
   • CUse a single IP address and configure proxy ARP for the other subnet
   • DCreate two VLANs and two SVIs, one for each subnet

   What is the purpose of a link-local IPv6 address on an Ethernet interface?

   • AIt is a globally routable address that can be used to reach the interface from anywhere on the internet.
   • BIt is used for communication on the local network segment only, and is automatically generated.
   • CIt is used to identify the interface in DNS for name resolution.
   • DIt is a temporary address used only during the DHCPv6 process.

   A network engineer is troubleshooting a routing issue on a Dell SONiC switch. The interface Ethernet 1/6 has been configured with the IP address 192.168.1.1/24, and the connected device is on the 192.168.1.0/24 subnet. The device can ping the switch's IP address, but the switch cannot ping the device. The engineer verifies that the interface is up and the IP address is correct. What is the MOST likely cause of this issue?

   • AThe switch does not have a default route configured
   • BThe interface is in Layer 2 mode
   • CThe device has a firewall blocking ICMP echo requests
   • DThe device's IP address is not in the same subnet as the switch

   A network engineer is configuring IPv6 on a Dell SONiC switch. The engineer assigns the global address 2001:db8:1::1/64 to Ethernet 1/8 and notices that the link-local address is automatically generated. The engineer needs to ensure that the link-local address is stable and does not change if the interface's MAC address changes. What should the engineer do?

   • AUse the eui-64 option when assigning the global address
   • BDisable IPv6 on the interface and re-enable it
   • CConfigure a static IPv6 route to the link-local address
   • DManually configure a link-local address on the interface

   What does the 'show ip interface' command display in SONiC?

   • AThe routing table for IPv4 routes.
   • BThe MAC address and VLAN membership of each interface.
   • CThe IPv4 address assigned to each interface and its prefix length.
   • DThe operational status of each interface (up or down).
